Qt-读取文件内容

1. 利用QFile和QTextStream

vector<QString> Dialog::ReadFile(const QString &fileName)
{
    vector<QString> contents;
    QFile file(fileName);
    if(file.open(QIODevice::ReadOnly | QIODevice::Text))
    {
        QTextStream textStream(&file);
        while (!textStream.atEnd()) 
        {
            contents.push_back(textStream.readLine());
        }
    }
    
    return contents;
}
